Application August 2, 1934, Serial No. 738,032

Claims.

My invention relates to syringes and the like, and more particularly to vaginal syringes of the bulb type.

Vaginal syringes of this type usually comprise 5 a bulb of soft rubber and a rubber tube and nozzle. Ordinarily, a hard rubber tube is used, which frequently causes lacerations and injuries of the tissue, and it is an object of this invention to provide a bulb syringe of this character which may be more readily manipulated, avoiding danger of injury to the tissues.

In the ordinary vaginal syringe heretofore used, the nozzle is provided with either transverse or longitudinal slits for the passage of the liquid therethrough. I found that more effective syringing or washing of the mucous membrane is obtained by arranging the openings in the nozzle so as to direct the flow of the liquid at an angle to the longitudinal axis of the nozzle.

A still further object of the invention is to provide means in the nozzle for effectively holding a medicinal or disinfectant tablet in combination with a tablet properly shaped to fit said nozzle.

5 Further important objects of this invention will be apparent from the following description of one embodiment of the invention, with reference to the accompanying drawing, in which:-

Figure 1 shows a side view of a syringe in ac- 30 cordance with this invention;

Figure 2 shows a longitudinal section through the syringe nozzle tube;

Figure 3 is a section on line 33 of Figure 1;

Figure 4 is a section on line 4-4 of Figure 2;

35 Figure 5 shows a longitudinal section through a portion of the nozzle and tube taken at right angles to that shown in Figure 2; and

Figure 6 shows a medicinal or disinfectant tablet for use with the syringe of my invention.

40 Referring to the drawing, the tube l is made of soft rubber and is formed on its exterior with a helical groove 2. A soft rubber tube may be manipulated more easily both during insertion and withdrawal of the nozzle, with no danger of in- 45 jury to the tissues, as will be well understood by those versed in the art. The helical grooves 2 which provide between them a wide raised portion of the tube body, also serve to conduct away any accumulated mucous which is removed by 50 the friction of the raised portions of the tube with the mucous membrane. Also, the helical groove 2 tends to cause the liquid from the syringe to take a circuitous path during its egress from the vagina and thereby massage the tissues.

55 The container 3 is preferably made collapsible so as to occupy very little space, and the tube l is formed at its open end with a circumferential recess 4 adapted to be engaged by a collar 5 integral with or insertable into the container 3. As the tube i is made of soft rubber, it is readily 5 removable from and insertable into engagement with the collar 5. The nozzle 6 is carried by or may form an integral part of the tube I. Said nozzle is provided with a series of circumferential apertures 1, forming passages extending through 10 the wall of the nozzle at an angle to the longitudinal axis of the nozzle and tube, as clearly shown in Figure 2. This arrangement of the apertures or passages 1 directs the flow of liquid downward and outward, and facilitates more ef- 15 fective cleansing of the mucous membrane.

The bulb or bag container is of the form described and disclosed in my copending application 624,280, filed July 2, 1932. The nozzle or rubber tube disclosed in such application is also provided with a recess at the tip thereof for holding a medicinal tablet, but the disclosure of the present invention is an improvement over that shown in said application.

It will be noted further that the nozzle is provided at its top with a groove or recess 8 adapted to receive and hold a correspondingly shaped medicinal or disinfectant tablet 9. The recess 8 is not in communication with the bore of the tube i, so as to prevent the pressure of the liquid emerging from the tube from expelling the tablet from its seat on the nozzle. The tablet when so used would simply be dissolved by the mucous discharge and would act as a medicinal or disinfectant agent. 5

While I have described one specific embodiment of my invention, it will be understood that various changes can be made therein without departing from the spirit and scope of my invention.

What I claim is:-

1. In a device of the character described, the combination with a soft rubber nozzle recessed at the tip, and having a protuberance in the bottom of the recess, whereby a recessed tablet may be placed in said recess in the nozzle tip so as to straddle the protuberance at the bottom thereof, and be fixedly held by the flexible sides of the recess.

2. In a vaginal syringe comprising a hollow tube formed with an external helical groove, the combination of a nozzle in communication with the interior of said groove, and having downwardly and outwardly extending passages in the walls thereof, and having a transverse imperforate recess formed in the tip of said nozzle, a protuberance in the bottom of said transverse recess, whereby a recessed tablet may be placed to straddle the protuberance and to seat upon the bottom of said transverse recess in the nozzle.

3. A nozzle for syringes made of flexible, soft rubber having a transversely extending imperforate recess across the tip thereof, with a central medial ridge in the recess, for fixedly holding a shaped tablet having a recess corresponding to the 'ridgqand plac'edja straddl e the same in the transverse recess'bf the tip? 4. In a vaginal syringe of the bulb type, the

combination of a soft flexible rubber nozzle with a transverse imperforate recess at the tip thereof, and having a ridge or projection in the said recess, whereby a recessed tablet may be held in the transverse recess of the tip so as to straddle the ridge or projection therein.

5. In a vaginal syringe of the bulb type, the combination of a soft, flexible rubber nozzle tube with a transverse recess at the tip thereof having no communication with the interior of the tube, whereby due to the flexible resilient lips f qrni lingfthsides of the recess a' solid'tablet may beheId-in the said recess of "the tip.
